▶ When designing thereservoir, ensure that there isanadequate distance between
thesuction line and thedrain line. This prevents theheated return flow from
being drawn directly back into thesuction line.
▶ Make sure that aminimum suction pressure of0.8bar abs.
(withoutchargepump) and/or0.6bar abs. (with charge pump) ispresent
atportS during operation, inall installation positions and installation locations
for theaxial piston pump, see Fig. 8. For additional pressure levels see.

The suction conditions improve with below- and inside-reservoir installation.
▶ Make sure that theworking environment attheinstallation site iscompletely
free ofdust and foreign substances. The axial piston unit should beclean
when installed. Contamination ofthehydraulic fluid can considerably affect
thefunction and service life oftheaxial piston unit.
▶ Use fiber-free cleaning cloths for cleaning.
▶ Use suitable, mild cleaning agents toremove lubricants and other heavy
contamination. Do not allow cleaning agents toenter into thehydraulic system.
7.3 Installation position
The axial piston unit can beinstalled inthe following positions. The pipeline routing
shown illustrates thebasic layout.
